Six Strong Quakes Strike Ring of Fire in past Week


In March, a magnitude 9.0 undersea megathrust earthquake, now known as the Great East Japan Earthquake, hit Japan.  One of the five most powerful earthquakes in the world overall since modern record-keeping began, the quake created a tsunami, killed more than 15,000, destroyed billions worth of infrastructure and caused a number of nuclear accidents.

On Sunday, a strong 6.4-magnitude earthquake struck near the coast of Indonesia’s Papua province.  There were no immediate reports of damage or tsunami warnings issued.

Aside from Indonesia, during the past week moderate to strong earthquakes have hit Japan; nations in the Pacific like Fiji; Latin American countries like Chile and Argentina; Alaska in the United States; and even Antartica.

The Irish Weather Online reported that 2011 is on target to record the largest number of earthquakes in a single year for at least 12 years.

According to the U.S. Geological Survey, earthquakes with magnitude of at least 5.5 that have hit during the past week include:
